myairbags myairbags.com Did not rebuild my airbag computer correct. New code that was not in it when sent to them is causing my airbag light to come on. duluth Georgia

Sent in my airbag computer to be rebuilt.  Got it back and installed it.  Deployment code is gone.  B0020 code is now in it.  They say it is a bad connection in my car. 

After spending 3 hours checking every connection tried a different computer in the car and the code was gone.  Put there computer back in it and code was back.  Informed them of this.  They say the problem is still in my car.  This is not true because with the other computer the code is gone.  They state the computer was tested before it left there shop and the problem is in my cars connections. 

I know this is not true as the other computer is still in there and there is no code.  They stated if I purchased a new computer from them they would take the rebuild price off from the new one.  Or I could pay for shipping bolth ways again and they would check it out. 

They would not stand behind the first one why should I spend more money with them.
